There's a useful part about the disconnected systems, connected people discussion I want to weigh in on, because it affected several engineering decisions we made in our support systems.
When overhauling our boat design, we overbuilt our solar, water, fuel, repair capacity, and food storage by about 2x our needs.
(Beyond carrying extra blankets, overbuilding shelter wasn't practical. Length and volume in a cruising/liveaboard sailboat is a liability.)
The doubled capacity is to share in everyday situations, and to help others in emergencies. Resilience = relationships + distributed community reserves, not isolation. In this build out we had the opportunity to put resources into that pool.
One of the things I value about the boating community is that it is a very strong community. Most people look out for each other, even on first meeting, and across every kind of social, cultural, and economic boundary you can imagine. Luxury cruise ships stop to help small boats in distress. People help each other with repairs when they have no common language. Gear is often lent out with no reasonable expectation of a return...and then the person helped might spend six months hunting down the lender to return a cookpot or foot pump anyway.
The community and the reserves are especially important in this environment because the line between friendly sharing and emergency support is fuzzy on a boat.
Encountering someone low on fuel, with a torn mainsail, missing a 8mm wrench, or with a contaminated water tank is "everyday". But it can also be one bad luck moment from becoming an "emergency". Storms, earthquakes, and municipal system failures are exciting but emergencies arrive at quiet, private scales as well.
